MPI support on core i5 750

I was trying to paralellize some math code (using freefem++) and after installing the MPI package and the MPI-compliant version of the software I ran the "mpisize" command, to my surprize, the answer came 0, meaning the system recognizes only one core in my quad core cpu.

I was wondering if this means that MPI only recognizes physical processors (as opposed to cores in each processor) or if I made a mistake during the installation of the mpi package or something.

Any help is appreciated.

  1. Seems I asked a hard one xD

    Anyway, thanks for reading!
  2. MPI is a communication protocol meant to 'sync' cluster like processing. Like muliple computers working on the same job. Have you checked into freefem Posix? I beleive thats the multi-threading stuff.

    Could you provide a link to some documentation or something like that, I searched for it on google and the freefem website, but couldn't find anything
  4. I beleive its freefem.org though I haven't used that stuff in a long time.
    I just checked , the sie is still there. I hope I steered you in the right direction.
